Solution of the Källén-Pauli Equation

Abstract
We give the relevant solution to the integral equation which Källén and Pauli have derived for elasticVΘ‐scattering in the Lee model. As an application of this result the exact Tamm‐Dancoff solution for the entire VΘ‐sector is obtained. This includes the amplitudes for VΘ‐ and N2Θ elastic scattering and VΘ‐N2Θ production, as well as their extensions off the mass shell.
